I have tailbone problems. When I sit on a hard surface for any length of time, it really bothers my tailbone. I can barely walk, definitely can't bend over. We went to Texas Roadhouse for dinner- wooden chairs.
Do you see a bump? I had one on my tailbone and it hurt like a motherfucker whenever I sat down. Turned out to be a cyst. : (
Oh shoot. No, I don't see anything. It's fine when I sit on a sofa, or my desk chair. It only bothers me on wood, concrete, bleachers. Really hard surfaces.
